Unify PCI configuration cycles

Split PCI IO configuration and MMIO configuration cycles to separate
files. Modern hardware does not use IO cycles for PCI configuration
after initial setup in bootblock.

Note that the pci_mmio_ and pcie_ functions were different in masking
the alignment for register address. PCI standard requires that 16-bit
and 32-bit configuration register writes do not cross boundaries.
